The Versa uses two filters: an engine air filter for the 1.6-liter engine and a cabin air filter for the HVAC system. Exact part numbers depend on your VIN, so verify with Nissan Parts or your dealer.
The following overview explains what each filter does, where it sits, and how to choose the right replacement for your 2021 Versa. It covers both the engine air filter and the cabin air filter, along with practical guidance on replacement intervals and fitment.
Engine air filter
Understanding the engine air filter helps ensure the engine receives clean air and maintains performance. Here are the key considerations when selecting this filter.
Common options and considerations before choosing:
- Type: Typically a disposable rectangular panel that fits into the engine intake box.
- OEM vs aftermarket: You can use Nissan genuine parts or reputable aftermarket equivalents that match the correct size and fit in the intake housing.
- Replacement guidance: Check the owner's manual for the recommended interval, commonly around 30,000 to 40,000 miles under normal driving, and inspect for excessive dirt or debris.
- Fit and seal: Ensure the filter seats properly with a clean housing seal to prevent unfiltered air from bypassing the filter.
A properly replaced engine air filter helps maintain engine power, responsiveness and fuel efficiency, while reducing the intake of dust and debris.
Cabin air filter
The Versa also relies on a cabin air filter to clean air entering the passenger compartment through the HVAC system. The location and replacement routine differ from the engine filter.
Common options and considerations before choosing:
- Type: Most cabin filters are disposable pleated panels; some trims offer an activated carbon version for odor control and extra filtration.
- Replacement guidance: Cabin filters are typically recommended for replacement every 15,000 to 30,000 miles or once per year, with more frequent changes in dusty environments.
- Compatibility: Select the filter that matches your Versa’s trim and HVAC configuration; aftermarket options should match the same dimensions and airflow pattern.
- Installation notes: The filter is usually located behind or near the glove box; follow service instructions to avoid tearing the filter or damaging clips.
A new cabin filter can improve interior air quality and HVAC efficiency, particularly for drivers with allergies or sensitivity to dust and pollen.
Finding the exact part numbers for your vehicle
Because Nissan may update part numbers across production runs and trims, the most reliable method is to use your VIN when shopping for parts. Check the official Nissan Parts website, contact a Nissan dealer, or consult your owner’s manual to confirm the precise engine and cabin filter part numbers for your car.
Auto parts retailers and dealer portals typically offer VIN-specific compatibility tools and cross-reference options to ensure you’re buying the correct filters for the 2021 Versa.
Summary
In brief, the 2021 Nissan Versa relies on two filters: a standard engine air filter for the 1.6-liter engine and a cabin air filter for the HVAC system. Always verify exact part numbers using your VIN and follow recommended replacement intervals to maintain engine performance, cabin air quality, and overall vehicle efficiency.
